distribution automation communication system is the core of distribution automation (DA).The system includes SCADA, feeder automation (FA), fault location data, load management, etc. It uses a variety of communication methods to monitor the distribution network in real time..
The networking of secondary power equipment such as FTU and DTU is a key link in distribution automation. Secondary equipment condition monitoring plays an important role in power grid management and fault monitoring.Due to the low requirements of many secondary devices for data flow and real-time data, cellular communication is sufficient to meet the operating requirements of the distribution network, and has the advantages of low investment, fast implementation, and fast communication establishment. Widely used in the construction of distribution automation communication networks.
distribution automation network requires networking equipment to have high reliability and stability.
power operation environment require that all equipment should be above industrial grade and can withstand serious electromagnetic interference.
power monitoring data requires that all communication terminal equipment must conform to the communication specifications of the power industry.
communication equipment needs to be connected to a variety of power automation terminals and requires strong compatibility of communication equipment.
Power Distribution Automation Cellular Solution
InHandInDTU324industrial cellular modems connect secondary equipment to the power wireless private network to provide reliable and stable network access for secondary equipment and ensure data communication between secondary equipment and master station.
secondary power supply equipment establishes communication with InDTU324 through serial port.
InDTU324 establishes a connection with the main station through the power private network, forwards the remote command issued by the main station of the power company to the secondary equipment, and transmits the remote communication and telemetry data of the secondary equipment to the main station system.
InDTU324 has the function of protocol conversion between power 101 and 104 protocol.
